Is "the end of the exponential" an established expression? There's no singularity in an exponential so the expression doesn't make sense to me. To me, it sounds like "the end of the exponential part", meaning it's a sigmoid, but that's obviously not what he means.
Why should it be obvious that this is not what he means? I struggle to think how he could mean anything else.
I’m guessing that Amodei meant it as a humorous inside joke.
It’s also shorthand for “the end of massive R&D capex” and “the transition to market capture”. The final stage, what McKinsey types call “harvesting”, is probably not on Amodei’s radar. Based on what I’ve seen of his public personality, he would see it as too philistine and will hand it off to another custodial exec.
